Application filed September 19, 1913.

To all whom it may concern: I

13c it known that l, Gnoncn O. RoBrNsoi a subject of the King of Great Britain, residing at Port Dover, in the county of Norfolk and Province of Ontario, Canada, have invented certain new and useful Improve ments in Cone-Baking Machines, of which the following is a specification. I

My invention relates to improvements in pastry baking mechanism, and more particularly to machines for baking ice cream cones, and consists essentially of a suitable frame or bench having slidable therein a plurality of transverse series of centrally divided female dies, the respective halves of said series being connected by folding links, corresponding male dies carried by a plate hingedly secured to the frame, heating appliances, and adjusting mechanism.

The invention has for its objects to provide a machine of the class specified which is designed to be superior in construction, more efficient in operation and production, to be capable of increased production, to be more durable, simple, and less expensive to manufacture than machines used heretofore for the same purpose.

These, together with other objects, 1nay be attained by the construction, combination and arrangement of the parts as will be hereinafter more fully described, illust ated in the accompanying drawings, and pointed out in the claim hereunto appended.

Reference may now be had to the acco1npanying drawings, in which: 7 V

Figure 1 is a side elevation of the entire machine showing the male and female dies engaged for baking;

Fig. 2 is a sectional side elevation of the machine taken on the line d4e in Fig. a, showing the parts open subsequent to the discharge of the finished cone;

Fig. 3 is a front elevation of the entire machine, showing male and female dies engaL'ed for baking.

Fig. a is a plan view of Fig. 2; and,

5 is a detailed plan view of the male die plate in baking position.

Similar reference characters refer to similar parts throughout the several views.

The front legs 2, 3; the rear legs 4, 5; forward and rear cross members 6, 7 respectively; and left and right lateral members 8, 9, respectively, constitute the frame of the machine. The aforesaid members are com- Specifieation of Letters 1?atent.

posed preferably of angle iron, and are bolted together as shown.

The female dies 10 are disposed in trans verse series,,centrally divided, the respec tive half portions of each series being formed in transverse members 11, which members contain the half portions of the adjacent female dies. Both end parts of the members 11 haveupper and lower horizontal holes through which are sleeved respective corresponding longitudinal rods 12, the ends of which rods are rigidly secured to the cross members 6 and 7.

The female die members 11 are connected laterally by collapsible links for the purpose of limiting the separation of the same to an intervening space just greater in width than the diameter of the female dies 10 when the same are together. lVhen the members 11 are in contact relation, the said links are folded as illustrated in Fig. 1 of the drawing.

Levers 1d are pivoted to a ring 15 rigid with extension b 'acket 16 secured to the forward legs 2 and 3. The said levers are connected at their upper end parts by a rod 1'? which serves as a handle for actuation purposes. Lateral links 18 are pivotally connected at their rear end to the former female die member, and are connected at their forward ends by 'a rod 19, the ends of which extend through and are slidable in longitudinal slots 20 in the levers i l. The rod 19 further serves a secondary purpose of augmenting the stability of the said levers.

Arms 21 provided with cross head 22, are hingedly secured to brackets 23 rigid on the cross member 6. A press screw 24, provided with hand wheel 25 and universal swivel 26, threads through the cross head 22. This press screw engages the forward female die member and retains said members in rigid contact each with the other while in closed relation. lVhile the female dies are in open relation, the press mechanism, hereabove described, assumes a depending position, as illustrated in Figs. 2 and 4c. v

The male dies, which are designated by 27, are rigidly secured to a plate 28 having a perimetric rib 29. The said plate is provided with integral rear arms 30 hingedly secured to brackets 31 rigid with the rear legs 5 and 6. When in closed position, the plate 28 rests flat against the upper surface of the female die members 11 which are flush with the top of the lateral members 8 9, and the rear cross member 7, the male les 27 being disposed in such position as to reg ister with the female dies 10, with circumferential intervening space between, as illustrated in Fig.1.

A press screw 32 is threaded through a transverse horziontal cross head 33 rigid with the lateral members 8, 9, and provided with a crank 34, and a universal swivel 35 engaging an arm 36 pivotally connected to the forward portion of the plate 28 by a screw 37. The said'arm is adapted to be horizontally swung to parallel the cross head 33 in order to escape the latter when the plate 28 is raised.

Stops 38 are provided on the arms 30, adapted to engage the brackets 31 in order to prevent the plate 28 from swinging too far back. 39 is a handle rigid with the plate 28, for the purpose of swinging the same. 40 is a handle for actuating the arm 36.

Heat is distributed from beneath to the diesby means of transverse gas burners 41 fed from a main 42. These burners are carried on a truck 43 provided with flanged wheels 44 running on transverse rails 45 suspended by brackets 46 rigid with the frame. The said burners are held rigid with the aforesaid truck by means of keeper straps 47. The said truck may be run clear from beneath the machine as shown in Fig.

4, a flexible gas tube communicating with the main 42 being provided to permit the same.

The upper portion of the dies are heated from burners 48 mounted on the plate :28 and held by a keeper strap 49. These burners are fed from the main 50 mounted on the arms 30, and communicate with a flexible tube.

Theoperation of the machine is as follows:

To put the machine in readiness for baking,thefemale dies 10 are closed, as shown Fig. 1. The truck 43 is now run to a position beneath the dies.

Then the necessary period has elapsed for baking, the male dies are again swung back, the truck run out from beneath the dies, and the female dies opened, as illustrated in Fig. 2. The cones now drop from between the die members 11, to a suitable container.

Having now fully described my invention, what I claim and desire to secure by Letters Patent of the United States, is

In a machine of the class described, the combination with a suitable frame structure, of a plurality of transverse female die members each comprising one half part of two separate series of female dies and having transverse holes in their end parts, rods rigid with the frame and sleeved through the holes in said members to permit longitudinal movement of the latter in the frame, folding links connecting members means for actuating said members in said movement, a press for securing rigid engagement of said members, a plate'hingedly secured to said frame, a plurality of male dies rigid with the plate and adapted to register and engage with said female dies, a press for assuring rigid engagement of the male dies between the female dies, and means for distributing heat to said dies.

In testimony whereof I have aflixed my signature.

GEORGE O. ROBINSON.
